csproj file only maintained for Mainline Visual Studio

Hi,

I am trying to use Visual Studio Code - Insiders edition as my main editor when working with Unity. Unfortunately Unity seems to only create/update csproj files if you have selected "Main Line Editors" as the "External Script Editor". ("Visual Studio 2017 (Community)", "Visual Studio Code"). But when using "Visual Studio Code - Insiders" it fails to recognize it as a valid version of "Visual Studio Code" and then it stops maintaining the csproj file that are necessary for Intellisense on VSCode.

Any way to work around this? My current setup is weird as hell:

1. Install both VSCode and VSCode Insiders
2. Select VSCode as the editor in Unity
3. Open a Script from unity
4. Close VSCode
5. Open VSCode Insiders

Continue to work until a new file is needed and then have to repeat steps 3,4,5.......

Suggestions?
